If you're going to go neoprene you should check out
Wet Okole. I think Cabelas distributes them as well.
They aren't the cheapest, but they're the best. Best fitting, best looking, etc. People think I have factory leather seats in my truck. They don't shift on the seats AT ALL because they are built custom for each vehicle. They're real comfy on long trips too.
Whatever neoprene you get, especially if it's a dark color, make sure you get some sort of UV protection spray for it.
I've kept mine treated and they look and feel like new after a year and a 1/2. They are light gray so that probably helps.
They'll send out sample color swatches too if you're concerned about appearance.
